Abstract
Size reduction of the dc-to-dc converter is most important issue in the switch-mode power supply. This paper presents general technologies and trends of high frequency switching of the dc-to-dc converter for the size reduction. Especially we discuss the problems of the magnetic amplifier as a highly reliable PWM element, when increasing the switching frequency. Then we describe the techniques of resonant converters and a novel method of regulating its output voltage with switching frequency constant.
